| Application | 1, 2-dichloropropane is mainly used in paint, ink, for the preparation of paint, ink, diluent and PVC adhesive, it is an excellent organic solvent, which can be used to make benzene-free banana water, polyurethane diluent and the like instead of benzene such as xylene, which is compatible with organic solvents such as benzene, ketone and Ester. As a by-product of the production of PO by The chlorohydrin method, it is used as the main raw material for the production of thinners and as a paint diluent. Low toxicity and environmental protection, instead of toluene benzene, is widely used in benzene free water. used as raw materials for organic synthesis, oil, fat solvent, detergent, resin, pesticide raw materials. Propylenediamine can be prepared by amination. 1, 2-dichloropropane and 1, 3-dichloropropene, as pesticide, I. E. As a drip admixture, D-D, Viden D,[8003-19-8]. D-D is a pre sowing nematicide, which can effectively control soil nematodes, including nodule nematode, grassland nematode, Thorn nematode, nematode, spiral nematode and sugar beet nematode. When the agent was applied to 15-20cm soil depth, the effect was the best. The product is phytotoxic, and the interval between application and planting must be at least 15d. Less toxic to bees. used as solvent and in organic synthesis |
